[BiO BB] installing blast

[ANGEL CARLOS ROMAN GARCI]

I've got a problem with the Standalone BLAST;

after I unzip and untar it, I put the .ncbirc file with
[NCBI]
Data="mypath/data"

and I unzip a db (Fasta preformatted);

right now, it should work, but no command is recognized in the console.
neither blastall, nor the others (but these commands exists in the
directory).

could you help me?
Thanks
